. Se tienen dos varillas, una de aluminio (∝=25 x 10^(-6) (°〖C)〗^(-1)) y otra de cobre (∝=16 x 10^(-6) (°C)^(-1)) de diferente longitud, tienen la misma área transversal, se le suministra a cada una cierta cantidad de calor hasta a que alcanzan la misma temperatura e igual longitud. La varilla de cobre debe ser

Aball is thrown upward in the air, and its height above the ground after t seconds is h ( t ) = 57 t − 16 t 2 feet. find the time t when the ball will be traveling upward at 14.25 feet per second.

How are calculation for velocity and speed different

In which situation has the independent variable for the experiment been changed? check all that apply. changed from counting the number of duckweed at day 0 and day 14 to counting them every day changed from testing duckweed growth in beakers to testing duckweed growth in large outdoor tanks changed from testing the effect of ph on duckweed growth to testing the effect of light levels on duckweed growth changed from testing the effect of acid ph on duckweed growth to testing the effect of basic ph on duckweed growth
